AHOMINY-MILL.

SPECIFICATION forming part of Letters Patent No. 305,546, datedSeptember 23, 1884. Application filed January 14, 1884. (No model.)

To all whom it may concern.-

Be it known that I, NOAH J. TILGHMAN, a citizen of theUnited States,residing at Salisbury, in the county of Wicomico and State of Maryland,have invented certain new and useful Improvements in Hominy Mills, ofwhich the following is a specification. My invention relates to animproved hominy-mill; and it consists in certain features ofconstruction and combination of parts, which are hereinafter described,and then claimed.

The invention referred to is illustrated in end elevation of the mill,in which the upper left corner of the case and upper part of cylinderare broken away to expose to view one of the saws. Fig. 2 is a view ofone pair of saws. Fig. 3 isaview of one of the perforated sections whichcompose the lower part of the cylinder. Fig. 4 is a longitudinalvertical section of the mill, except the hopper, upper part of the case,and cylinder. Fig. 5 is a view of the removable slide. Fig. 6 is aviewof the perforated or continuous diseh argeslide. Fig. 7 is a detailview showing the slide-grooves in the cylinder.

The machine is supported on legs A, and consists of a cylindercomposedof the upper part, B, and lower part, B, which parts areseparable on a horizontal line at the bearings c of the saw-shaft d. Theupper part, B, of the cylinder is inclosed by a case, E, both of whichare removable. A hopper, F, surmounts the case, and a passage, 9, leadsfrom the hopper to the eylinder,while a slide, h, at the bottom of thehopper controls .the passage. A square shaft, d, has journaled endsresting in bearings c at the ends of the cylinder, and a series ofstraightbladed saws, I, are mounted on the shaft. A hub, j, has a squareeye, cl, adapted to fit on the shaft, and two flanges, is, thinner thanthe hub. The flanges are diametrically opposite each other, and to eachof them a straight saw, I, is secured by rivets or bolts Z. Thus bymeans of the hubs the saws are mounted in pairs, and the hubs arereadily slipped on the end of the shaft. (See Fig. 4.) One half of thesaws-- that is, every other pairextend in one direction, while the otherhalf are placed so as to extend crosswise of the first half, asindicated in Fig. 1. The saws turn in a vertical plane. The entirelength of the square shaft is occupied by the saw-hubs, and as these areclose together and in contact there is no need to fasten each oneseparately. By this construction the removal of all or any of the hubsand saws from the shaft for sharpening is easily effected, and is doneby simply lifting the shaft from its bearings and slipping the hubs fromthe shaft. The shaft has a loose pulley, n, and a drive-pulley, n, andturns in the direction toward which all the saw-teeth point, asindicated by the arrow in Fig. 1. The shelled corn passes from thehopper into the cylinder, where it is subjected to the action of thestraight saws I, revolving with shaft d. These thin saws readily passthrough the bulk of corn in the cylinder, effectually hull the kernelsof corn, remove the germ, and split the kernels, thereby doing all theworl; of converting the corn into hominy. I find these saws never getchoked. They are peculiarly well adapted to do good work, do it rapidly,and with as-little power as or less power. than some machines. The lowerpart, B, of the cylinder is perforated, as at p, and I have constructedit in sections, q, which are secured by screws 1" to longitudinal bars0* below, extending from end to end of the cylinder. These sections arepreferable to forming the lower half of the cylinder in a single piece,because in case of damage at one place repairs may be easily and cheaplymade by inserting a single section. The perforations p are for theescape of the chaff or hulls and germs. A dischargeslot, s, is formedthe entire length of the lower part the cylinder. At each edge of theslota groove, t, is formed (see Fig. 7) in any suitable way, and a bar.U, slides endwise into these grooves, and thereby closes thedischarge-slot. To allow the hominy to be discharged, the slide-bar Ushould be entirely drawn out, whereupon the hominy would all dischargeinstantaneously. This arrangement is desirable in. some work; but inproducing a different character of product it is desirable to have acontinuous or perpetual discharge. I therefore provide a secondslide-bar, V, having holes or perforations to larger than those in thelower part of the cylinder, and of proper size to allow. the exit (ofhalfgrains but to prevent the escape of square. eyes d,

adapted to slip loosely on said whole grains of corn. This perforatedslide; shaft and rest against each other, and probar, being in positionto close the slot 8, will vided on opposite sides with thin flanges isprovide for the continuous discharge of the and straight thin saws I,substantially as and I 5 5 hominy. Thus the operator can adapt the maforthe purpose describe y chine to do the work required.
